PAPER com Application filed July 21,, 1931.

This invention relates to containers formed of paper and the primary object is to provide, a container with reinforcing or stifiening ribs outstanding therefrom and extending longitudinally thereof.

A further object is to provide a container which can be formed in the shape of an ordinary milk bottle or other'desired configurations, the surplus paper supplied by the blank being taken up by the ribs on the container.

Another object is to assemble the bottom of the container with the body portion thereof in a new and novel manner, there being a tie device combined with the container for maintaining the shape thereof adjacent to the bottom.

' With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings the preferred shown.

Referring to the figures by characters of 1 designates a blank of suitably prepared paper stock which, in the structure illustrated, has straight side edges 2 converging toward one end, the said ends of the blank being curved as shown at 3 and 4. Adjacent to the curved edge 3 the blank is formed with parallel score lines 5. Between the edge 3 and the. score lines the blank is formed with inwardly extended crimps 6 which are spaced apart regularly and are located adjacent to the lower ends of outwardly projecting crimps 7 extending from the score lines 5.toward the edge 4. The lines along which the blank is to be crimped have been indicated at 8 in Figure 1. v

The side edges 2 are adapted to lap and to be aflixed in any manner desired. By producing the crimps 7, the surplus stock in the bottom portion of the blank above the score line can be taken up during the annular contraction of the body while it is being brought to substantially cylindrical form. The upper ends of the crimps or ribs 7 can taper awa gradually so as to merge into the smooth intermediate portion 9 of the bottle which can be shaped readily under pressure to produce the desired neck contour. This will be apparent by referring to Figure 8. 1

A paper neck ring 10 of suitable thicknes can be secured around the small upper end of the blank. This ring, while forming a part of the container, constitutes no part of the present invention:

The bottom closure of the container consists of a disk 11 having a flange 12 formed with an annular series of outwardly extending crimps 13. These crimps are equal in number to the crimps 7 and are spaced apart the same distances. The bottom closure is adapted to be inserted into the container so that its crimps 13 will become seated in the lower end portions of the crimps 7 close to the score lines 5. This location of the parts has been shown in Figure 6. Thereafter that portion of the blank containing the crimps 6 is bent upwardly into the space surrounded by the crimped flange 12 so that thecrimps 6 will thus become seated in crimps 13 as indicated in Figures 7 and 9.

Following the assembly of the parts as herein explained a metal hoop 14 is placed about the container substantially in the same plane with the bottom closure and is crimped as shown at 15 so as to straddle and tightly grip all of the ribs or crimps and hold them from spreading where they interfit.

A container such as herein described can be produced readily by the use of suitably shaped forms for crimping the blanks and shaping the stock at points removed from the crimps and the resultant structureis not only advantageous because of its simulation of an ordinary milk bottle, which enables it to be handled in the same manner as a milk bottle, but also because the ribs stiffen the container and provide a means whereby it can be firmly gripped.

The container can be manufactured very cheaply so that it can be discarded after use.

Obviously instead of making the container in the form of a bottle, it can be made of other shapes. For example, and as shown in Figures 10 and 11 the container can be made substantially cylindrical, the body 16 thereof being formed with longitudinal ribs or crimps 17 and the bottom closure 18 being assembled therewith in the same manner as heretofore described. A binding hoop 19 can also be used, this being simllar to the hoop 14. The container can be provided with a top closure 20 which is a duplicate of the bottom closure so that a sealed package will thus be produced.

In Figures 12 and 13 there has been illustrated a substantially conical container 22 formed in the same manner as heretofore described. This container has the longitudinal ribs 23, the bottom closure 24 and the inturned crimped portion 25 for seating in the crimped flange of the bottom container which, in turn, is assembled with the body portion as heretofore pointed out. A band 26 corresponding with bands 14 and 19 is also used. In this form of container a substantially cylindrical neck 27 can be used, this being located above the ribs 23 and provided with an annular bead or rib 28 forming a sealing shoulder for engagement by an over-all cap 29.

Any of the containers herein described can be provided with'a smooth lining 30. One of these has been shown in Figure 10 and serves to close the shallow grooves or depressions formed within the container by the crimps 17 A lining of this type is particularly useful if the container is desi ed to hold jellies or other viscuous jelly-l e substances. By providing such a lining in a cylindrical container or in an inverted conicalt container, the contents can slip readily from the container, carrying the lining therewith.

Obviously containers of shapes differing from those described can be made within the scope of the present invention. In every case the container can be formed primarily of a substantially segmental blank as shown for example inFigure 1 so that the blank can be contracted to the desired shape by crimping and compressing it to produce the r1 5.

1. A paper container having an annular series of longitudinal crimps providing stiffening ribs, an end closure inserted within the body and having a crimped portion seated in andsurrounded by the series of lon 'tudinal crimps, and means outside of the Indy for holding the interfitting portions of the crimps on the body and the inserted closure against spreading.
